Murarrie is your answer. 20 -25 mins to the cbd by train. Straight on the gateway motorway to be at the Goldie or the sunny coast in an hour. If you are game you can also get to straddie in about an hour on the passenger boat. Only hazards are aircraft noise and coal train noise if too close to railway line. It's also a fairly cheap suburb to get into. A bit of a sleeper actually. Check it out for yourself.
